After all I've changed the meaning of this existing user option:

,---- w3m-refresh-minimum-interval
| Number of seconds used to override the meta refresh a page specifies.
| If the meta refresh seconds the page specifies is less than this value,
| this will be used instead of that.

The default is now five seconds.  This is enough for a user to
glance the page, to kill the loop, or not to apply heavy load to
a cpu and a network, isn't it?
(To kill the loop, simply kill the *w3m* buffer.)

As for Google search results, emacs-w3m still inhibits the zero
seconds refresh.  I'll remove it when Google comes to its sense,
though Google has not clarified it up yet.
